I was trying to manually set the env variable
I created my own 0.9.0.yaml, and created a configmap loading it by
kubectl create configmap game-config --from-file=/local_path.../knative.dev/serving-operator/files/knative-serving/0.9.0.yaml
Then, this is the operator deployment yaml I used:
apiVersion: apps/v1
kind: Deployment
metadata:
name: knative-serving-operator
spec:
replicas: 1
selector:
matchLabels:
name: knative-serving-operator
template:
metadata:
annotations:
sidecar.istio.io/inject: "false"
labels:
name: knative-serving-operator
spec:
serviceAccountName: knative-serving-operator
containers:
- name: knative-serving-operator
image: knative.dev/serving-operator/cmd/manager
imagePullPolicy: IfNotPresent
#command:
# - ["bin/sh", "-c", "ls /etc/kodata/knative-serving ; echo the path of KO_DATA_PATH: $(KO_DATA_PATH)"]
env:
- name: KO_DATA_PATH
value: "/etc/kodata/"
- name: POD_NAME
valueFrom:
fieldRef:
fieldPath: metadata.name
- name: OPERATOR_NAME
value: "knative-serving-operator"
- name: SYSTEM_NAMESPACE
valueFrom:
fieldRef:
fieldPath: metadata.namespace
- name: METRICS_DOMAIN
value: knative.dev/serving-operator
volumeMounts:
- name: game-config-volume
mountPath: /etc/kodata/knative-serving
volumes:
- name: game-config-volume
configMap:
name: game-config
I expected that operator pod will read the env variable KO_DATA_PATH, and load the manifest from the mounted path "/etc/kodata/knative-serving". And it is true that this is something we surely can do.
However, I came across the following log:
{"level":"info","ts":"2019-10-30T17:50:08.438Z","caller":"logging/config.go:103","msg":"Logging level set to info"}

The log has been frozen here. manifestival is trying to Reading manifest, but no further movement.
I added a snippet in the source to find out what is going on. It turned out that there are literally 3 files under the path /etc/kodata/knative-serving: ..data, ..2019_10_30_17_50_07.090926616 and 0.9.0.yaml. It seems that the package manifestival is unable to exclude the files, which are not in the correct yaml format.
I suppose this is a bug for the lib manifestival to improve. For example, we can exclude the files not in correct yaml format.
@jcrossley3 I would love to hear from you. Thx.
